K-CMM Software
The K-CMM Help Pages provide you with documentation on the use and the
specifications of the K-CMM software, independently from the camera or CMM
host program used.
The K-CMM software works as an interface between the camera system and the
CMM host software as depicted in the picture below. It calculates the accurate
position of the probe tip mounted on the SpaceProbe and sends this coordinate
to a CMM host program over a serial or a TCP/IP connection. The CMM host
software processes the coordinates received from K-CMM to build planes, lines,
circles, … with these coordinates.
The customer can choose the CMM host software freely. Interfaces for the most
common CMM software are available in K-CMM (Powerinspect, Metrolog II,
Metromec, …).
For camera or CMM host program related matters, the reader is referred to the
Help Pages of the corresponding product.
The K-CMM Help Pages contain:
• instructions on how to get started with the software
• step-by-step procedures for the most important features
• troubleshooting pages
Some PC-experience and a basic knowledge of the English language are
required to understand these Help Pages.

How do I start a measurement ?
2.1.1
Guidelines for heat up time
Make sure to take into account the necessary heat up time of the equipment.
Normal heating up time is 45 minutes.
If you transport the camera to room at a different temperature you have to take
into account an extra heating up time.
This extra heat up time will be around 1 hour for every 10 degrees of
temperature difference.
Heat up time = 45 min + 60 min / 10°C
Examples:
1. The system was stored over night at 10 °C and is started up in the
morning in a room at 20 °C. The heat-up time is 1 ¾hour. (45 minutes
after the switch on + 60 minutes because of the 10° temperature
difference )
2. The equipment was stored in the measurement room the night before but
not switched on. The heat-up time is now 45 minutes. (45 minutes heatup time when the system has been switched on)
3. The system was stored in the measurement room over night and was
switched on the whole time. You can start the measurement immediately
in the morning.
2.1.2
How to hold the probe
It’s best to use both hands while measuring. You can use one hand to hold the
probe and your other hand to guide the probetip on the surface.
If you use the probe with only one hand you risk to deform the probetip
( especially with longer tips ). It is also more difficult to steady the probe while
measuring. Therefore, you should support the probe tip to prevent tip flexibility
and reduce the contact force.

2.1.3.2
Make all cable connections and start PC, controller and camera.
Make sure K-link has been switched on and that the camera and
controller are detected . Start KLink if not automatically started.
Open K-CMM and start it
Assemble the probe tip (appropriate tip extension piece, etc.) and
calibrate it: KCMM – Calibration. If you’re not sure about
the procedure please read chapter 2.2.1. Calibrate a
probe
You can check the camera accuracy and if needed correct it by
measuring the K Reference bar. If you’re not sure about
the procedure please read chapter 2.2.3. Perform a K
reference measurement
Try to position the object and/or camera in such a way that you can reach
all relevant points with the Probe. Easiest to check this is via KView or
with KCMM (see where LED is green).
Try to avoid as much as possible that IR light shines into the camera field
(e.g. direct or indirect sunlight). This can be checked via KCheck , light
intensity in camera field without LED’s should never be higher than
around 10% of the maximu m white bar length.
Preparing the part
TurbuLED
If you are not sure on the stability of the environment ( e.g vibrations, draught
etc… ), it is recommended to use a TurbuLED. This feature will give you an
idea of the stability of the environment.
• The TurbuLED will intervene if necessary during the measurement by
turning the feedback LED orange or red. If the environment is too
unstable, the TurbuLED will color the feedback light red and the measured
points will not be accepted.
If you’re not sure about the procedure please read chapter 2.2.6. Use a
TurbuLED
Dynamic Reference
It is recommended to use a Dynamic reference when:
• The object is not very stable; there is a risk it will move during the
measurement.
• The measurement object does not fit completely in the camera field.
During the measurement the camera will need to be moved slightly to
measure all points. To do this without losing the previous measurement
data, you need a Dynamic Reference.
• Vibrations of the environment (less than 5 Hz).
If you’re not sure about the procedure please read chapter 2.2.3. Use a
Dynamic reference
KRYPTON Help Pages on K-CMM
Page 10 / 79
JUMP function
When larger camera displacements are needed the Dynamic Reference is no
longer sufficient. In these cases the JUMP function can be used.
•
Attach JUMP points (minimum 3) to the object or use points on the object
(e.g. small holes). Make sure the JUMP points can be measured in the
different camera positions you want to use.
•
Activate the JUMP function during the measurement when it is needed.
2.1.3.3
2.1.3.4
Beginning the measurement
•
•
Open K-CMM and start it
Once K-CMM has been started, calibrate the position of the
TurbuLED and/or the dynamic reference.
•
Start the measurement software (e.g. PowerInspect), make sure the
connection is made
Tips for usage
Do’s
•
•
•
•
•
Try to position the camera as close as possible to the measurement
object (minimum 1.5 meter).
Try to measure as much as possible when the feedback LED is green, i.e.
try to direct the SpaceProbe as much as possible to the camera.
Try to place the SpaceProbe as perpendicular as possible during
measuring. This is to ensure the direction of the tip compensation is
correct and is very important when measuring slots, diameters, etc. .
Place LED’s of the Dynamic Reference directed to the camera. Do not
use them under large camera angles.
If you’re not sure of the probetip calibration, recalibrate the probe tip.
Don’ts
•
•
Try not to use an extension piece for the probe when it’s not needed. A
longer probe tip makes the measurements less accurate.
Do not use the LED’s of the Dynamic Reference under large camera
angles. Place them directed to the camera.

How To
2.2.1
Calibrate a probe
To calibrate a new probe-tip you can follow the following procedure:
1. If not already done, mount the probe-tip on the probe.
2. Click the CALIBRATE PROBE button
Calibration software.
to start the Probe
Notice: If the K-CMM software is already started and you mount a new probe-tip
on the probe, the software will recognize the probe automatically. On the screen
a question will pop-up asking you if you want to re-use a previous calibration of
this probe-tip or if you want to re-calibrate the probe. If you choose to re-use the
previous calibration, the K-CMM software will work with this calibration. If you
choose to re-calibrate the probe-tip the calibration program will be launched and
you can follow the steps below to calibrate the probe-tip again.
3. Put the calibration station at 2.5 m from the camera in the center of the
measurement volume.
4. Click on the first button
at the bottom of the Probe Calibration screen
or press the exterior button on the probe. This will start the Origin Calibration
procedure.
5. Place the probe tip in a calibration base in which we can rotate the probe in
all directions with a free motion of +- 45° in two perpendicular directions.
6. Now we must in total take at least take 20 points by moving the probe around
the fixed point in the fixture. The points can be measured by pressing one of
the interior buttons on the probe. On the screen two colored bars appear,
giving an indication of the quality of the applied rotation of the probe. The bars
shrink from the red to the green zone if a sufficient excitation is imposed
(sufficiently large angles around the axis of the probe).
7. A good strategy for Origin calibration is showed in the following picture:
KRYPTON Help Pages on K-CMM
Page 12 / 79
a.) Rotate the probe to the left (with respect to the camera) while taking
measurement points until the first colored bar has shrunken to the yellow
zone. Best is to take 5 points or more in this direction.
b.) Rotate the probe to the right while taking measurement points until the
first colored bar has shrunken to the green zone. Best is to take 5 points
or more in this direction.
c.) Move the probe forward while taking measurement points until the second
colored bar has shrunken to the yellow zone. Best is to take 5 points or
more in this direction.
d.) Move the probe backwards while taking measurement points until the
second colored bar has shrunken to the green zone. Best is to take 5
points or more in this direction.
e.) The figure in the middle of the screen shows the amount of points you
have taken.
8. While taking the measurements a third colored bar to the right of the two
colored bars, appears. This bar gives an indication on the uncertainty of the
probe tip position during origin calibration. This bar should stay in the green
zone to guarantee the standard accuracies.
9. When you have finished taking points, press the exterior button again to finish
the origin calibration.
KRYPTON Help Pages on K-CMM
Page 13 / 79
10. Optional:
a.) When you also want to do a direction alignment, press the Direction
Alignment button
at the bottom of the Probe Calibration screen.
b.) For the direction alignment we must measure at least 2 points while
moving along the shaft of the probe-tip. We take 2 points: one point as a
reference point and a second one that simulates a take-away point /
approach point. This is graphically represented in the following picture.
Take first point on the work piece surface
Take second point in mid air
11. When you have finished the probe calibration, press the Save button
to save your calibration and then the Exit button
screen.

Frequently Asked Questions on Probe calibration
What are the errors in CMM when measuring with large probe tips
Q1 Some customers use large probe tips. The question rises as to what the
errors are when using tips of lengths such as 100 and 500 mm.
A:
A lot will depend on the orientation excitation.
With no orientation excitation, with tips of up to a 100 mm long, the
measurements should stay within specifications.
With 500 mm length, it is very difficult to estimate, but a loss of factor 2 can be
expected. Moreover, because of bending of the probe tip with a 500 mm long tip,
errors can rise to 0.5 mm and more. Avoiding bending of the tip is something that
is very operator-sensitive.
Notice: If you want minimalise the risk of increased measurement uncertainty you
can also not allow any orange LED measurements.
The picture below represents the accuracy as a function of the probetip length
compared to the probe length

2.2.2.1
Perform a K Reference measurement
When and how to use the K Reference procedure
The K Reference is a calibrated length standard that comes optionally with a KCMM measurement system. By measuring this calibrated length standard and
comparing this measured length with the nominal length of this reference bar, the
accuracy of the K-CMM measurement system can be checked. In addition, when
the system has suffered from environmental influences (e.g. temperature shocks
during traveling), the K Reference procedure will compensate for any of these
influences and bring the system back to its highest accuracy.
It is recommended to use the K-reference procedure :
•
•
•
After the system has been transported
Before a measurement if the temperature change after the last K
reference is larger than +/- 2 °C.
Whenever you are in doubt of the accuracy of the system, you can use
this procedure as a verification tool. (e.g. this could be used as a quick
daily verification of the system )
How to use the procedure:
Make sure the system is heated up properly and adapted to the environment
temperature. For more information on this, please read the chapter
“2.1.1 Guidelines for heat up time”.
Verification procedure :
•
•
Start the 7 step procedure like described under chapter 2.2.2.2.
Measure only 2 positions:
•
•
Z-direction of the camera
1 of the four spatial diagonals
If the result of this measurement is OK
( e.g. measured values are in tolerance before compensation )
• You have verified the accuracy of the equipment,
you can continue now with the measurement
If the result of this measurement is not OK
( e.g. measured values are not in tolerance before compensation )
• You have to do a 7 step K reference procedure, like
described below. This will allow you to compensate
for the errors you are measuring.
• Compensate after you have measured all 7
positions.
• After this compensation you should redo the
verification procedure.
KRYPTON Help Pages on K-CMM
Page 16 / 79
2.2.2.2
K Reference 7 step procedure
To perform an accuracy verification and/or compensation with the K Reference
follow this procedure:
1.
Mount the K Reference bar on the portable stand that comes with it.
2.
Make sure you have calibrated the probe with a tip of 10 mm diameter. To
calibrate a probe see chapter 2.2.1. Calibrate a probe.
3.
Make sure the reference bar is positioned in Zone 2 of the camera field.
The middle of the bar should be positioned at 3.5 from the camera.
4.
If you haven’t started the K-CMM software yet, push the START
MEASURING button.
5.
Push the K Reference button
to start the K Reference
procedure The MODE window will show that you are in K Reference
mode.
6.
The bar has to be measured in seven positions, each with the bar placed
along a certain direction:
−
X-direction of the camera;
−
Y-direction of the camera;
−
Z-direction of the camera;
−
the four spatial diagonals.
7.
Put the K Reference bar in one of the above positions.
8.
Now you can start measuring the K Reference bar; the INFORMATION
window will show you the number of the point you’re about to measure.
9.
Put the probe in the measurement hole on one end of the K Reference
and push one of the trigger (interior) buttons on the probe to take a
measurement point.
KRYPTON Help Pages on K-CMM
Page 17 / 79
10.
In the same way measure a point in the hole on the other side of the K
Reference without moving the K Reference. Now you have measured the
length of the K Reference once. Suppose you moved the bar while
measuring and you want to delete the last point you have taken. Keep
one of the inside buttons pressed until you hear a long beep. If you then
let go the button, the last point will be deleted.
11.
Move the K Reference to the next of the positions mentioned in step 5.
12.
Now measure the length of the K Reference again as described in steps
8, 9 and 10. If this was the last position you have measured continue to
step 13. You can check which intermediate positions have been
measured already, by pressing the external button. ( See picture below )
13.
Click the exterior button on the SpaceProbe to finish the measurements.
14.
If you have not measured every position yet, the following screen will pop
up showing you which positions haven’t been measured yet:
KRYPTON Help Pages on K-CMM
Page 18 / 79
15.
If you want to measure the missing positions click one of the interior
buttons on the SpaceProbe or click the “Measure More Poses” button on
the screen and return to step 6. If you want to continue without the
missing poses, click the exterior button on the SpaceProbe or click the
“Start K Reference” button on the screen.
16.
A window with the results of the measurements will now appear on the
screen:
17.
In this window you will find the measured lengths and the deviations from
the nominal value for each position in which you have measured the K
Reference. Now you have four options available:
•
Accept: if the Initial deviations on the measurements (this means
without a compensation) are within the specified tolerance, the system
is still perfectly aligned and you can accept this verification
measurement. If the system is not within tolerance anymore (without
doing a compensation), it is not possible to click the Accept button.
•
Cancel: if you do not want to take any action concerning the accuracy
of the system click the Cancel button.
•
Compensate: if the system has suffered from environmental
influences and it isn’t within the specified tolerance anymore, the
software can compensate for this. The software can only calculate a
compensation if all of the seven positions (three axes and four spatial
diagonals) have been measured. If this is the case the deviations after
compensation will be shown in the results window in the column
“Deviation”. The compensate button is only available if the results are
within tolerance after compensation.
KRYPTON Help Pages on K-CMM
Page 19 / 79
•
17.
Reset: if you want to clear any previous compensations that have
been done, click the Reset button.
After clicking one of the four buttons the K-CMM software returns to the
normal measuring mode. Now you can start the measurements on your
workpiece with a guaranteed accuracy of your K-CMM system.
Notice: Instead of measuring the K Reference by measuring just one point on
each side (in one and the same position of the K Reference), it is also possible to
measure two or more points on each side of the K Reference. The software will
then calculate the average of these points and will use that value to calculate the
measured length. For example, you can measure, in one position of the K
Reference, two points on one side and after that two points on the other side. The
software will calculate the average of the first two points and the average of the
second two points. The measured length in this position will then be calculated
with these two averaged values.

K reference procedure is not successful, cannot press the “compensate
button”
Q2: After doing the 7 step K reference procedure, the values shown in the
“deviation” column on the right are within spec, however it is still not possible to
press the compensate button.
A: This could have a very simple explanation: the “Tolerance” value is too low.
(see picture here under). In the picture here under the “Acceptance Tolerance” is
set at 0.01 mm while the measurements range from –0.124 mm to 0.078 mm.
To solve this problem do the following:
• Go to the file "c\ …\Kcmm\bin\infieldwin.ini"
• Open this file
• Look for the place where you see: "Tolerance = x.xx”, where x.xx is the
value of the tolerance. In our example according to the picture below this
would be 0.01.
• Change this value to 0.127.
• Double click the file "c\Kcmm\bin\infieldwin.exe" and now you should be
able to press the same window as below except you should be able to
press the button “compensate.”
Unable to measure certain axis during K reference procedure
Q3: While performing a K reference procedure I cannot seem to be able to
measure certain axis of the camera. How come?
A:
This occurs mostly with the Y-axis when the camera is vertical and the X-axis
when the camera is horizontal.
a) It is often the case that the camera is tilted to the opposite side in comparison
to the reference bar. Because this angle is to big, the software will not interpret
the position of the reference bar as the direction that the user wants. This
problem is very easily solved by turning the reference bar 180 degrees around
the axis coming out of the floor on which the reference bar is standing.
b) Perhaps there is still a JUMP active. As a result of this some directions may
be seen differently by the camera then they really are. Delete the JUMP points in
case you don’t need them anymore.

2.2.3.1
Use a Dynamic reference
Dynamic reference proce dure
The dynamic reference function allows you to filter out movements or vibrations
of the workpiece or to interrupt measurements and move the camera system and
still continue to work in the same reference system.
If you are working in an unstable or industrial environment ( e.g. temperature
changes, air flow, vibrations etc … ) it is recommended to use a TurbuLED.
The TurbuLED can be used in combination with a Dynamic Reference and gives
extra information about the environment.
To use a TurbuLED, please read the chapter on TurbuLED procedure.
To use the dynamic reference, follow the following procedure:
1.
To make a dynamic reference some reference points need to be placed on
the workpiece. These reference points can be markers (plain LEDs) or
omnidirectional references (3 LEDs rotatable around a sphere). Attach the
reference points (at least 3 and maximum 64) that will serve as a dynamic
reference, to your workpiece. This can be done by using glue, double-sided
tape, fixation clamps, etc. The actual position of the reference points on the
workpiece is of no importance but the points should be spread over the
measuring field as good as possible. Also do not place the reference points
on one line.
2.
For the connection of the reference points to the controller we must make a
difference between the markers and the omnidirectional references.
a. For the markers: Connect the markers to one or more Strober
units. When connecting the markers always start connecting from
port 1. When you want to use more than 3 or 6 markers, you can
connect the Strober units in series.
b. For the omnidirectional references: Each omnidirectional reference
has its own Strober unit. These Strober units have to be
connected in series. Here it’s important though that you connect
the omnidirectional references in the same order as in which you
have calibrated them. For more information on how to calibrate
these omnidirectional references see the Omnidirectional
Reference calibration procedure page
3.
Connect the first Strober unit of the chain to the third port on the controller
(a dynamic reference always has to be connected on the third port of the
controller). If you want to use port 2 you need a transition piece.

4.
In K-CMM, go to the Dynamic reference tab in the <Settings><User
settings> menu. If the <User settings>menu appears in grey, you’re
probably still in measuring mode. In that case, click on the STOP
MEASURING button to stop measuring.
5.
Put a checkmark at the ‘Activate dynamic reference’ option to activate the
dynamic reference.
6.
Fill in your desired values for the Maximum deformation and Maximum
displacement of the markers (see the Maximum deformation and Maximum
displacement page in the Appendix for more information).
7.
Fill in the number of reference points you attached to the workpiece. This is
the number of markers or the number of omnidirectional references
connected to the controller.
8.
Choose whether you are going to use markers or omnidirectional
references as reference points. In case you use omnidirectional references
you must also enter the calibration file of the references you want to use.
9.
You can fill in the name of the file that will store the current setup of the
markers. By default this filename is extref.dat. If you already have a
previously defined dynamic reference you want to use again, fill in the
appropriate filename or click the Load button to search for this file on your
PC.
10. Click the OK button to leave the Settings menu.
11. When returning to the K-CMM main screen you will notice that the Dynamic
reference status window becomes green indicating that the dynamic
reference is active.
12. Click the START MEASURING button. Now an initial position of the
reference points must be measured. To this position all further
measurements will be recalculated. Click the Calibrate Reference LEDs
button
to measure the initial position of the reference points. A
progress bar will appear on the screen. Make sure that during the
measurement of the external references all the LEDs are visible.
13. After the initial position has been recorded you are ready to do your
measurements on the workpiece. From this point on the camera and the
workpiece can move in reference to each other without influence on your
measurements.

14. To deactivate the dynamic reference option, return to the Dynamic
reference tab in the <User settings><Settings> menu and remove the
checkmark at ‘Activate dynamic reference’.
Maximum deformation and Maximum displacement
The maximum deformation value defines the maximum allowable movement of
the markers in relation to each other.
By default this value is set to 0.3 mm but for accurate measuring a value of 0.1
mm is advised.
The maximum displacement value is used by K-CMM when not all the markers
defining the dynamic reference, are visible anymore. In this case the software
can still use the dynamic reference based on the markers that are still visible and
under the condition that the workpiece is not moved. However when the
workpiece is moved and less than 3 markers are visible, the software cannot
match the old and the new position of the markers anymore. Therefore a
maximum displacement value is used that defines the maximum allowable
movement of the markers when less than 3 markers are visible.
By default this value is set to 0.2 mm but for accurate measuring a value of 0.05
mm is advised.
When one of these values is exceeded an error message will be displayed in the
Information window on the K-CMM main screen.
Notice: When you want to use a certain dynamic reference again afterwards, just
go to go to the Dynamic reference tab in the <Settings><User settings> menu
again. Activate the dynamic reference and fill in the appropriate parameters. In
the “Active reference” field enter the name of the file that contains your dynamic
reference. Click “OK” to leave this menu. When you start K-CMM now, your
dynamic reference will be active again.
2.2.3.2
Troubleshooting a Dynamic Reference
The Information window shows the error message "Reference has moved"
When you have defined a dynamic reference for your workpiece, the software
can determine the position of the workpiece unambiguously based on the
markers that make up the dynamic reference.
However when less than three markers are visible for the camera system, the
software can only determine the correct position of your workpiece if it doesn’t
move in the mean time. So when the camera sees less than three markers and it
notices that one of the visible markers moves, it displays the error message
"Reference has moved".
To solve this problem check the following things:
- Make sure all the markers are visible for the camera system by removing
any obstacles. Now K-CMM can determine the position of your workpiece
again and the error message will disappear.
- Check the Maximum displacement value in the Dynamic reference tab in the
User settings menu. By making this value larger you can allow more
movement of the markers before an error message is displayed.
- Apply more markers to your workpiece so that in every measuring position of
the workpiece, at least three markers are visible.
KRYPTON Help Pages on K-CMM
Page 24 / 79
The Information window shows the error message "Reference is deformed"
When you have defined a dynamic reference for your workpiece, the software
can determine the position of the workpiece unambiguously based on the
markers that make up the dynamic reference.
However when one of the markers moves in relation to the other markers, the
position of the workpiece cannot be determined unambiguously anymore. K-CMM
than displays the error message "Reference is deformed".
To solve this problem check the following things:
- Make sure the markers are firmly attached to your workpiece. Preferably a
glue or double-sided tape is used to attach the markers.
- Make sure you attached the markers to a rigid structure that does not
deform during your measurements.
- Check the Maximum deformation value in the Dynamic reference tab in the
User settings menu. By making this value larger you can allow more
movement of the markers in relation to each other, before an error message
is displayed.
- If you notice that a marker fell off, you have to recalibrate the dynamic
reference by clicking the Calibrate Reference LEDs button
realign the object before continuing measurements.
. and
The information window shows the error message "Reference not optimal"
When applying markers to your workpiece you should always try to distribute
them as good as possible in the measurement volume you want to measure in.
This means, try to cover the largest surface possible and do not attach the
markers on one line.
The K CMM software has a built in check to see whether the markers you applied
to your workpiece form a ‘stable’ reference. If the (visible) markers do not form a
stable reference the information will show the error message "Reference not
optimal".
To solve this program check the following things:
- Make sure you haven’t placed the markers on one line.
- If you are using more than three markers and several markers are not
visible, make sure that the markers that are visible are not on one line but
are also well distributed.
Notice: At least three markers are needed to create a dynamic reference. If you
use more than three markers, it is allowed that markers become invisible. The
only conditions that have to be fulfilled are that at least three markers stay visible
and that the visible markers form a “not too sharp” triangle. More specific, the
largest base of the triangle must be smaller than four times the height of this
triangle.

2.2.3.3
Frequently Asked Questions on Dynamic Reference
Loss in accuracy due to a Dynamic Reference
Q1: What is the accuracy lost with the use of an Dynamic reference?
A: The accuracy lost is dependent of the use of the Dynamic reference. It is very
important to keep in mind the following rules in order to minimize the error:
• Put the leds used for the Dynamic reference as in a triangle as large as
possible ( see picture above )
• Try not to measure too far away from the Dynamic reference with the
probe.
• Try not to move the Dynamic reference too much, as it is only useful to
compensate small vibrations.
• Make sure that the Dynamic reference leds are of the same type as the
probe.
• Make sure that the strobers used for the Dynamic reference are of the
Krypton type.
• It is very important to use the same type of leds for external reference as
for the probe
If all these conditions are fulfilled, then the accuracy loss in minimal and can be
estimated at approximately 0.1 mm.
Error can run up:
• If above rules are not followed
• If the Dynamic reference leds are of the OD100 type and the probe leds
are of the ceramic type. If than the external reference is put in a small
equilateral triangle of 200 mm/side and the camera is moved from 3000
mm to 4500 mm in the Z then the additional error is approximately 0.6 to
0.9 mm. If then an additional movement is done of 1000 mm in the X
direction then the total error of the external reference can run up to 1.5
mm.

2.2.4
Perform a camera jump
2.2.4.1
Jump procedure
The Jump function allows enlarging the measurement volume by repositioning
the camera and using intermediate points as reference points. This enables you
to do measurements on one workpiece in several camera positions. This can
solve problems of visibility of the probe from the camera, caused by obstacles.
1.
To perform a jump the K-CMM software has to be in measuring mode. So
first click the START MEASURING button if the software isn’t in measuring
mode yet.
2.
Click on the JUMP button
3.
A window appears, showing you a list of intermediate points used for the
camera jump. The list of points is identical to the last saved configuration.
•
If the list is empty, only ‘New point’ is mentioned in the window. This means
that the system is ready.
•
If the points in the list are of no use, the list can be cleared by clicking the
DELETE ALL button
in the main K-CMM screen.
.
4.
A number of ‘Intermediate points’ (minimum 3) should be measured (see
Choice of intermediate points in the Appendix for more information). These
points must be visible from the sensors future location. When there is any
doubt concerning the visibility, some extra points can be measured for
safety. The number of intermediate points is unlimited.
5.
The next step is to reposition the camera in order to complete the
measurement.
6.
A click on the NEW JUMP button
, stops the acquisition mode
of new intermediate points and all points in the list turn red. The software is
now ready to measure the points again.
7.
From this new position the intermediate points should be measured again.
All intermediate points can be measured in sequence. When you want to
KRYPTON Help Pages on K-CMM
Page 27 / 79
measure the points in random order, simply click on a specific point with the
mouse and measure it.
8.
After having measured at least three points, the software displays the
Residual behind each point. The residual is the difference between the
theoretical value and the measured value after a best fit. The blue bar that
appears beneath the measured points indicates the overall Residual.
9.
When the Residual values are extremely high, an error has been made
(possibly two points are not corresponding, you missed one point in the
sequence or you measured a wrong point). To solve this, mark the point
with the highest residual by clicking the Mark point button
. If
afterwards all the residuals are fine, it means that this disabled point was
not measured the right way. You can measure this point again by clicking it.
If the residuals don’t change significantly, it’s recommended to remeasure
the points.
10.
By clicking the OK button
, the software automatically
calculates a transformation between the initial position of the camera and
its new position. As a result all the coordinates transferred through the
serial link are expressed in the initial coordinate system. In the K-CMM
main screen you will notice that the Jump status window turns green
showing that the Jump function is active.
When you want to jump again from this new camera position to another position
follow the following procedure:
1.
Click the Jump button
2.
If you need some new points to perform the jump, click on ‘New point’ in
the points list and measure the necessary additional points. If no new
points are necessary, continue to the next step.
3.
Click on the NEW JUMP button
become red again.
4.
Measure a least three of the points again to define the new camera
position.

jump.
to activate the new camera
To de-activate the Jump function, do the following:
1. Click the Jump button
to open the points list again.
2. Click the DELETE ALL button
.
3. The software will ask you if you are sure to delete all the measured points.
Click "Yes” to confirm this.
4. Click the OK button to leave the points list. The Jump function will be deactivated now. The Jump status window will turn grey again.
A minimum of three points has to be measured when the camera is in its initial
position. Measuring four points is recommended for redundancy.
These points should also be easy to measure repeatedly, so avoid measuring
points on a plane or a surface. Instead try to measure points in holes or corners
that are easy to find again.
For optimal measurement conditions these points should be as far from each
other as possible and should cover, if possible, the whole measurement volume.
Notice: The Jump is transparent for the measurement software. This means that
after executing the jump function, all coordinates sent to the measuring system
are expressed in the original part coordinate system. The measurement software
does not notice the camera jump.
2.2.4.2
Troubleshooting a JUMP
The Residual values are extremely high
When you want to perform a jump, a set of points has to be measured in the two
camera positions. The software will calculate a best fit between these two sets of
points. The deviation from this best fit for each point is displayed as the residual.
When these values are very high this means that one or more points have been
measured incorrectly.
To solve this problem, follow the next steps:
1. Search for the point with the highest residual.
2. Click on this point to activate it.
3. Click on the Mark button
to disable the point. This point will now
be left out in the calculation of the best fit between the two sets of points.
KRYPTON Help Pages on K-CMM
Page 29 / 79
4. If the residuals are all fine now, this point was measured incorrectly.
Measure the point again making sure you measure the same point as you
did in the initial camera position.
5. If the residuals aren’t fine yet, repeat steps 1 to 4 until the residuals adapt
normal values.
- As an alternative you can measure all the points again by clicking on the
NEW JUMP
button. All the points turn red again and you can
start measuring them again. Make sure you measure the points in the
correct sequence.

Use a TurbuLED
When and how to use a TurbuLED
The TurbuLED allows you to monitor the presence of any “turbulences” (that can
influence your measurements) by constantly monitoring one marker.
It is recommended to use a TurbuLED:
•
•
In an industrial environment
In any other environment where measurements can be influenced by:
- Changing temperature
- Vibrations
- Important air flows
How to use the procedure:
Make sure you the system is heated up properly and adapted to the environment
temperature. For more information on this, please read the chapter
“2.1.1 Guidelines for heat up time”.
What to do if the TurbuLED is out of tolerance:
If this happens try to identify the cause.
• If it is obvious that the camera or the object is moved
o Verification of the camera by the K Reference procedure is not
needed but can be usefull. ( For this please read the chapter on
the K Reference procedure )
o Object needs to be realigned, once this is done the TurbuLED can
be recalibrated and the measurement can continue.
o If you want to avoid having to realign the part every time the
camera or the part moves, you should use a Dynamic Reference
or Omnidirectional Reference.
( For this please read the
appropriate chapters )
•
If you are not sure about the cause or if you think it is a change in
temperature.
o Verification of the camera by the K Reference procedure should
be done. ( For this please read the chapter on the K Reference
procedure )
o If needed perform a 7 step K reference procedure and
compensate for the new environment temperature. ( For this
please read the chapter on the K Reference procedure )
o Object needs to be realigned, once this is done the TurbuLED can
be recalibrated and the measurement can continue.
o If you found the cause of the environment instability ( e.g.
changing temperature ) try to fix this cause if possible.
o If you want to avoid having to realign the part every time the
camera or the part moves, you should use a Dynamic Reference
or Omnidirectional Reference.
( For this please read the
appropriate chapters )
KRYPTON Help Pages on K-CMM
Page 31 / 79
2.2.5.2
TurbuLED procedure
To use the TurbuLED, follow this procedure:
1. Mount an extra LED on your measurement object and connect it to the
last free entry on the strober unit that is connected to the second port on
the controller. For example, if you already have connected four LEDs to
use as a dynamic reference, connect the TurbuLED on the fifth port of the
Strober unit. If you do not have any other LEDs connected, connect the
TurbuLED on the first port of the Strober.
2. In the K-CMM software, go to the <Settings><Machine settings> menu.
Go to the <Measurement Parameters> tab and put a checkmark at
‘Activate TurbuLED’.
3. Specify the tolerance parameters:
−
Position Tolerance (mm): if the position of the TurbuLED changes
more than this tolerance an error message “Environment not
stable” will appear. Also the Feedback Led on the SpaceProbe will
become orange and measurements are only possible if the ‘Allow
orange LED measurements’ is enabled in the <Measurement
Parameters> tab. It is recommended to use the systems
specification 0.09 mm if the TurbuLED is placed in Zone 1 and 2
and 0.19 mm if the TurbuLED is placed in Zone 3.
−
Standard Deviation (mm): if the standard deviation on the position
of the TurbuLED changes more than this value during the
measurement of a point with the SpaceProbe, an error message
“Environment not stable” will appear. Also the Feedback Led on
the SpaceProbe will become orange and measurements are only
possible if the ‘Allow orange LED measurements’ is enabled in the
<Measurement Parameters> tab. A recommended value is 0.05.
−
Maximum Peak Duration (s): if one of the previous tolerances is
passed longer than the specified time (e.g. in case the
measurement part has moved) the error message “Environment
not stable” appears. The Feedback Led on the SpaceProbe will
become red and no further measurements are possible.
A recommended value is 3 seconds.
4. Click the OK button to leave the Settings menu.
5. Click the START MEASURING button.
KRYPTON Help Pages on K-CMM
Page 32 / 79
6. Click the Calibrate Reference LEDs button
. The software will
now capture the initial position of the TurbuLED. This position will serve
as the reference position; any changes from this position will be seen as a
“turbulence”.
7. After the initial position of the TurbuLED is captured, the TurbuLED is
activated and any change in position will be shown by a colored bar on
the right side of the screen.
Notice:
• When you click the TurbuLED button, the software will also capture
the initial position of the LEDs that are used for a dynamic reference
together with the position of the TurbuLED.
• You can use a TurbuLED in combination with a Dynamic Reference. If
you do this, the TurbuLED position will be compensated by the
Dynamic Reference.
2.2.5.3
Troubleshooting a TurbuLED
The Information window shows the error message "TurbuLED not calibrated!"
If you activate the TurbuLED, an initial position of the TurbuLED has to be
recorded. If this initial position has not been measured yet, the Information
window will show the error message “TurbuLED not calibrated!”.
To solve this problem, click the Calibrate Reference LEDs button
. The
software will now measure the initial position of the TurbuLED. Make sure the
TurbuLED is visible at all times during the measurement of this initial position.
The Information window shows the error message "Environment not stable"
When the TurbuLED function is activated, the position of the TurbuLED is
constantly monitored. When for whatever reasons the position of the TurbuLED
changes (e.g. the workpiece is standing on a vibrating floor), the Information
window will show the error message “Environment not stable” to warn you that
you’re measurements will suffer from this unstable environment.
If this “disturbance” only lasts for a short time (shorter than the time specified in
the “Maximum Peak Duration” field in the <Settings><Machine
settings><Measurement Parameters>) the feedback LED on the SpaceProbe will
turn orange. In this case the TurbuLED is probably attached to a workpiece that
is vibrating or you have entered very severe tolerances for the TurbuLED. You
will only be able to measure now if you have activated “Allow Orange LED
Measurements”
in
the
<Settings><Machine
settings><Measurement
Parameters>.
KRYPTON Help Pages on K-CMM
Page 33 / 79
If this “disturbance” last longer than this “Maximum Peak Duration” the workpiece
your TurbuLED is mounted on, has probably drifted away (e.g. somebody has
pushed it). In this case the feedback LED on the SpaceProbe will turn red. Now it
is impossible to take measurement points.
So in order to measure in a “stable environment” take care of the following things:
- Place your workpiece on a stable floor that doesn’t vibrate or in case the
floor does vibrate, use the dynamic reference to compensate for these
vibrations.
- Make sure nobody pushes or moves your workpiece during your
measurements.
- Avoid temperature drifts in your measurement room.
Please be aware that the TubuLED does not function with ProbeCal.

2.2.6.1
Use a Omnidirectional Reference
Omnidirectional Reference calibration procedure
For a Dynamic reference you can use either bare LEDs or Omnidirectional
references as reference points. Before using the Omnidirectional references
however, the relation between the LEDs and the centre of the sphere (which will
serve as the reference point) must be derived first. Therefore they must first be
calibrated in more or less the same way as the SpaceProbe. This procedure
describes step by step, how to calibrate these Omnidirectional references.
1. To make a Dynamic reference at least three reference points are
necessary. So make sure you have a set of at least three Omnidirectional
references.
2. Fix the Omnidirectional reference (with a magnet, a clamping base, …) so
that it cannot move anymore.
3. Connect the first of your set of Omnidirectional references to the second
port on the controller.
4. Open the K-CMM software.
5. Push the CALIBRATE PROBE button
.
6. The Probe calibration program will automatically activate the SpaceProbe,
but since we do not want to calibrate the SpaceProbe go into the “Probe”
menu and choose “Activate” to remove the checkmark and de-activate the
SpaceProbe.
7. Go into the “Probe” menu again and select “Open”.
8. Now a default definition file for an Omnidirectional reference must be
loaded. You can find such a file in c:\Kcmm\probe\omnidir.prb.
9. Activate the Omnidirectional reference by going into the “Probe” menu
again and selecting “Activate”.
10. You will notice that now, three buttons appear on the screen of the Probe
calibration program, showing the visibility of the LEDs on the
Omnidirectional reference.
KRYPTON Help Pages on K-CMM
Page 35 / 79
11. Click the Origin calibration button
to start the origin calibration of
the Omnidirectional reference. Two colored bars, ranging from red to
green, will appear on the screen. These bars will lower when taking
points, while rotating the Omnidirectional reference in two perpendicular
directions (from back to front and from left to right). For a good calibration
the bars should lower until they are both in the green zone.
12. Take measurement points by clicking the Manual Trigger button
.
After each point, rotate the Omnidirectional reference a little bit in one of
the two perpendicular directions. A good strategy for taking the points is
shown in the following picture:
a.) Rotate the Omnidirectional reference to the left (with respect to the
camera) while taking measurement points until the first colored bar has
shrunken to the yellow zone.
b.) Rotate the Omnidirectional reference to the right while taking
measurement points until the first colored bar has shrunken to the green
zone.
c.) Move the Omnidirectional reference forward while taking measurement
points until the second colored bar has shrunken to the yellow zone.
d.) Move the Omnidirectional reference backwards while taking
measurement points until the second colored bar has shrunken to the
green zone.
KRYPTON Help Pages on K-CMM
Page 36 / 79
13. The figure in the middle of the screen shows the amount of points you
have taken.
14. While taking the measurements a third colored bar to the right of the two
colored bars, appears. This bar indicates the uncertainty on the position of
the sphere centre point during origin calibration. This bar should stay in
the green zone to guarantee the standard accuracies.
15. When you have finished taking points, press the Origin calibration button
again to finish the origin calibration.
16. The calibration of this Omnidirectional references is now ready. This
calibration should now be exported to a calibration file. Therefore go to
the “Probe” menu and choose Export.
17. The software will now ask for a filename to save the calibration to. Enter a
filename (f.e. c:\Kcmm\probe\calibomnidir.prb). This will be the filename
you have to enter as the calibration file in the “Calibration file” field in the
Dynamic reference tab. If you selected a filename that already existed,
the software will ask you to append the calibration data to this file. Choose
“No” to overwrite the file. Be sure, however, not to overwrite the
omnidir.prb file!
18. Now the next Omnidirectional reference must be calibrated. Disconnect
the previous Omnidirectional reference from the controller and connect
the next one.
19. Follow steps 11 to 16 to calibrate this Omnidirectional reference.
Afterwards continue to step 20.
20. When the software asks you for a filename to save the calibration to, use
the file in which the calibration of the first Omnidirectional reference was
stored (f.e. c:\Kcmm\probe\calibomnidir.prb).
21. The software will now ask if you want to append the calibration data to
this file. Choose “Yes” to do so.
22. If this was the last Omnidirectional reference to be calibrated, continue to
step 23. If you have some more Omnidirectional references to calibrate,
go back to step 18.
23. When you have finished the calibration of the Omnidirectional references,
click the Exit button
KRYPTON Help Pages on K-CMM
to exit the calibration program. When the
Page 37 / 79
software asks to save the changes in the file “omnidir.prb”, choose “No” to
discard the changes.
Notice: It is important that you remember the order in which you have calibrated
the Omnidirectional references. When you will use them later on to create a
Dynamic Reference, you should connect them in series in the same order as in
which you have calibrated them. So the first Omnidirectional reference you have
calibrated will also be the first one in your chain of Omnidirectional references for
the Dynamic Reference and has to be connected to the second port on the
controller.
2.2.6.2
Troubleshooting an omnidirectional reference
Since Omnidirectional references are also a sort of dynamic reference, it is
advised to read the Troubleshooting chapter on Dynamic Reference as well.
In addition to that error messages related to Omnidirectional references may
have other causes:
• K CMM gives error message “Reference deformed”. Make sure all the
Omnidirectional references have been calibrated and all the data are saved in
1 file (all calibrations points are amended to the first calibration file).
Try if slightly turning the Omnidirectional references solves this problem. If
needed please increase the values for maximum deformation under User
settings Dynamic reference
• Attach the Omnidirectional references via a strober and a cable to one of the
front ports on the controller (not to port 1!). Make sure to do this in the same
sequence in which they were calibrated.
• Has the right calibration file for the Omnidirectional references been selected?
Change this, if needed, under KCMM – User settings, Dynamic reference,
Active reference.

Use the image function
Image procedure
The image function allows you to record the 3D coordinates of several markers,
attached to your workpiece.
To use the image function, follow the following procedure:
1. Attach markers (maximum 247) to the points on your workpiece you want to
measure the coordinates of. This can be done by using glue or double-sided
tape.
2. Connect the markers to one or more Strober units. When connecting the
markers always start connecting from port 1 to port 6. When you want to use
more than 6 markers on one controller port, you can connect the Strober units
in series.
3. Connect the Strober unit to the controller.
4. In the K-CMM software go to the Image tab in the User settings menu. Here
you must fill in the amount of markers you attached to each of the ports on the
controller. Notice that the ports 3 and 4 are called respectively Dynamic
Reference and Image 1 in the Image tab.
5. You can choose to use a certain trigger for the Image function. The different
possible triggering options are:
− Distance trigger: the software will measure the position of the markers
again, each time the first LED moves a certain specified distance;
− Time trigger: the software will measure the position of the markers again
with a certain specified time step.
− No trigger: the software will measure the position of the markers once and
after that the Image function will be disabled and the IMAGE status window
will turn grey again. Now you can measure additional points on the
workpiece with the probe.
6. Put a checkmark at ‘Activate Image Mode’ to activate it and click the OK
button.
7. When returning to the K-CMM main screen you will notice that the IMAGE
status window has turned green, meaning the Image function is active.
8. Put your CMM host software in a mode where it’s ready to receive the
coordinates of the makers.

9. To start the measurements click the START MEASURING button. The KCMM software will now start scanning for the markers attached to your
workpiece and immediately send the 3D coordinates of these markers to your
CMM host software.
10. The Image function will keep being active until you disable it in the Image
tab in the <Settings><User settings>menu.
Notice: The image function can also be used while the dynamic reference
function is active. In that case the absolute movement of the image-markers is
compensated according to the dynamic reference-markers.
If you select markers on port 3 (called “Dynamic Reference” in the Image tab) to
be used in the image function, the markers of the dynamic reference will be sent
as image-points as well.

• Is the “Image” function activated ?
• Have you put in the right LED configuration ( number and port )
• Is the measurement software ready to receive the points? (e.g. in
Metrolog II, single point option has to be activated )
• Are the LED’s visible ?
Only some LEDs have been measured:
• Is the option measure invisible LED’s activated ?
• Are the LED’s visible ?
• Have you put in the right LED configuration ( number and port )
• Is the measurement software ready to receive multiple points ? (e.g. in
Metrolog II z.B. you have to select a repeat measurement)

Turn the camera’s axes
Several CMM host softwares (f.e. PCDMis, Metromec) are designed to work
mainly with static measurement machines and have certain functions that
assume you’re working with a measuring device that has fixed, predefined
machine axes. The key issue in most of these cases is that the Z-axis should be
pointing more or less upwards.
To be able to work with these softwares, a set of batch files is available that can
reorient the Z-axis of the K 6D Camera system when used with the K-CMM
software.
The use of these batch files is very simple and straightforward:
1. Place the camera in front of the workpiece you want to measure so that all
the points you want to measure are inside the camera volume. The
orientation of the camera (horizontal or vertical) is of no importance.
2. Look at the coordinate system drawn on the camera to see which axis is
lying mainly vertical. Also look in which direction this axis is pointing (up or
down).
3. Before you start the K-CMM software, find the batch file that matches the
axis of the camera and the direction you just defined and execute it. F.e. if
the axis that is lying mainly vertical, is the X-axis and this axis is pointing
downwards, search for the file “X down” and execute it.
4. Now you can start the K-CMM software. You will notice that the Jump
function will be active due to the camera axes reorientation.
5. You can now start your measurements. The Z-axis of the camera will now
be pointing upwards.

Do a profile measurement using only K-CMM
The Profile measurement allows automatically measuring sections of your
workpiece. This enables you to measure workpiece sections without you having
to worry about taking measurement points that are exactly in the section plane.
To take measurement points you move the probe as close along the section line
as possible. The K-CMM software will automatically take measurement points as
long as you move the probe within a specified distance from the section plane
(the tolerance field). A measurement point is automatically taken each time you
move the probe a specified distance within this tolerance field.
To perform a Profile measurement, follow the following procedure:
2.
First you have to define a workpiece coordinate system in your CMM host
software. This coordinate system will be used to define your section
plane. For more information on how to define a coordinate system in your
CMM software refer to your CMM software user’s manual.
3.
Next you will have to measure at least three points and export the
coordinates of these points both in workpiece coordinates and in CMM
coordinates. Make sure you remember the name of the files you exported
the coordinates to. As an example we will use the filenames CMM.txt and
workpiece.txt with the coordinates of the points expressed in the CMM
coordinate system and in the workpiece coordinate system respectively.
Notice that currently this option is only supported in K-CMM for files
generated with the CMM-software Metromec©.
4.
Now go back to the K-CMM software and click the START MEASURING
button
.
5.
Click on the Profile Measurement button
settings screen.
6.
In the Alignment field, fill in the filenames of the two files you just exported
from your CMM software. In our example we fill in CMM.txt in the Machine
field and workpiece.txt in the Workpiece field (you can also locate both
files on your PC by clicking on the Change file button). After filling in a
filename, click on the Load button to load this file.
7.
Next you have to define your section plane in the Plane settings field:
•
to bring up the Profile
Indicate whether your section plane is parallel to the YZ-plane (Xdirection), the XZ-plane (Y-direction) or the XY-plane (Z-direction).
KRYPTON Help Pages on K-CMM
Page 42 / 79
•
Specify the offset from this plane to the section plane.
8.
Specify a tolerance value in the Tolerance field. This value defines the
offset from the section plane within which measurement points will be
taken.
9.
Specify a Distance Trigger value. This value specified how far the probe
has to be moved before a new measurement point is automatically taken.
10.
Now you can click the Activate button to activate the Profile
measurement function.
11.
Move the probe as close along the section line on your workpiece. The KCMM software will now automatically take measurement points as you
move the probe.
12.

2.2.10 Do a hole measurement using only K-CMM
The Hole measurement function is a tool that helps you to measure holes. The
difficulty in measuring holes is to position the probe tip on the section in which
you will define the hole.
The K-CMM software helps you with this in a way that measuring holes becomes
very easy. You simply measure a plane that is parallel to the hole and specify an
offset from this plane to define the plane in which you want to measure the
diameter. When starting your measurements you can simply move the probe in
and out of the hole along the side of the hole. The K-CMM software will
automatically take measurement points each time you cross this plane you
specified.
To perform a hole measurement, follow the following procedure:
1.
To start the Hole measurement the K-CMM software must be in
measuring mode, so click on the START MEASURING button in the KCMM main screen to start the Measuring mode (make sure the Image
mode is not activated).
2.
Next click on the Hole Measurement button
Plane settings for the Hole Measurement function.
3.
First measure three points that will define a plane, parallel to the plane of
the hole you want to measure. Click on the Measure Plane button to start
measuring these three points.
4.
To define the plane of the hole, fill in an Offset value that specifies the
distance from the first measured plane to the plane of the hole.
5.
Specify a tolerance value in the Tolerance field. This value defines the
offset from the hole’s plane within which measurement points will be
taken.
6.
Specify a Distance Trigger value. This value specified how far the probe
has to be moved before a new measurement point is automatically taken.
7.
Now you can click the Activate button to activate the Hole measurement
function.
8.
To take measurement points, move the probe in and out of the hole along
the side of the hole. The K-CMM software will now automatically take
measurement points as you move the probe around the perimeter of the
hole. To define a hole, a minimum of three points is necessary, but K-
KRYPTON Help Pages on K-CMM

forward, the directory, chosen for the installation, will be called the K-CMMdirectory in these Help Pages.
The installation program creates (if it not already exists) a program group Krypton
(under the Windows menu <Start> <Programs>) that contains shortcuts to the KCMM software components (that can be found in the ‘bin’-subdirectory of the KCMM-directory).
The following components can be found here:
• Probecheck: a utility to check if the probe is connected properly and if all the
buttons, feedback lights and temperature sensors on the probe are working
well.
• K-CMM: the main program that will set up the communication between the
measuring device and the CMM host program.
Notice: In order to work with the K-CMM software, software needed for the
camera configuration (delivered with the K6D camera system) and a CMM host
program should be installed as well. This CMM host program is not supplied with
the K-CMM software, unless specified in the sales contract.

The main screen
The K-CMM program is the main program that will set up the communication
between the measuring device and the CMM host program.
K-CMM is started by clicking the K-CMM icon
in the <Krypton><K CMM>
group. After clicking this icon the K-CMM main screen will appear as shown in the
following picture:
To start the communication between the measurement probe and the CMM host
program, simply press the START MEASURING button (the button with the
green ‘play’-sign). When you’ve finished your measurements you can press the
STOP MEASURING button again to stop the interfacing.
Notice: Before starting a measurement, make sure that you have installed the
K6D program on your PC and that you have configured it in the right way (see
K6D Help pages).
When the START MEASURING button is pressed for the first time after starting
the K-CMM software, the program will show a message on the screen that a new
probe-tip has been detected.
KRYPTON Help Pages on K-CMM
Page 47 / 79
If the probe-tip that is used has already been calibrated, you can choose to reuse this calibration by clicking on the RE-USE-button on the screen or by
pressing the exterior button on the probe.
If the probe has not been calibrated before or has to be re-calibrated, the probe
calibration procedure can be started by clicking the RE-CALIBRATE-button on
the screen or by pressing one of the interior buttons on the probe. For more
information on the calibration of the probe please read chapter
2.2.1 How to calibrate a probe
Notice: If the tip you mounted on the probe was previously calibrated with another
probe, the software will notice this. If you would try to re-use the previous
calibration (by pressing the RE-CALIBRATE-button), the software will still start
the calibration program. This is done in order to prevent you from measuring with
an incorrectly calibrated probe.
3.1.5.2
Buttons

The CALIBRATE REFERENCE LEDs button
Whenever you use the Dynamic Reference function or the TurbuLED function,
the initial positions of the LEDs used for the Dynamic Reference or the
TurbuLED, have to be measured. Measuring these initial positions is done by
clicking the CALIBRATE REFERENCE LEDs button. A progress bar will appear
showing you the progress of the measurement. Make sure all the LEDs are
visible at all times during the measurement of the initial position.
After an initial position is measured, this position will be taken as the reference
position and all deviations will be calculated relative to this position. The
reference position will not change until you click the CALIBRATE REFERENCE
LEDs again to measure a new reference position.
The K REFERENCE button
This button launches the procedure to measure the K Reference (a precalibrated
length reference). By measuring this reference length, the accuracy of the system
is calculated and any environmental influences on the accuracy can be
compensated.
When you click this button the software switches to ‘K Reference’ mode (as can
be seen in the MEASURING MODE window). Now the length of the K Reference
bar has to be measured in several directions: along the three axes of the camera
and along the four spatial diagonals. The INFORMATION window will show the
amount of points measured so far. After measuring these lengths, the software
will tell you which directions are still missing. You can now choose to start the K
Reference without these directions or go back to measure these missing
directions.
KRYPTON Help Pages on K-CMM
Page 49 / 79
When starting K Reference you will get an overview of the measured lengths in
each position together with their deviations from the nominal value (Current
Deviation). If you have measured all of the seven positions, the software is able
to calculate a compensation for the deviations and you will see a list with the
initial deviations (Initial Deviation) and a list with the deviations after
compensation (Deviation). You will however, only be able to click the
“Compensate” button if the deviations after compensation are within the specified
tolerance.
Notice: Before starting measurements that require the highest accuracy or when
the system has been transported, it is advised to perform a verification with the K
Reference.
In general it’s also advised to perform a verification with the K Reference on a
regular basis (e.g. every week) to make sure that the K CMM system reaches its
specifications.
For a step-by-step description of the measurement of the K Reference,
refer to the chapter 2.2.2 How to perform a K reference measurement
The PROFILE MEASUREMENT button
The Profile measurement function allows automatically measuring sections of
your workpiece. This enables you to measure workpiece sections without you
having to worry about taking measurement points that are exactly in the section
plane.
KRYPTON Help Pages on K-CMM
Page 50 / 79
You simply define a main plane that is parallel to your section plane by entering
the plane’s direction (X, Y or Z). Next you specify the distance from this main
plane to the section plane. To take measurement points you move the probe as
close along the section line as possible. The K-CMM software will automatically
take measurement points as long as you move the probe within a specified
distance from the section plane (the tolerance field). A measurement point is
automatically taken each time you move the probe a specified distance within this
tolerance field.
For step-by-step instructions on how to use the Profile Measurement
function refer to the chapter
2.2.9 How do I do a profile measurement using only K-CMM
When you click the PROFILE MEASUREMENT button the following screen
appears:
Alignment
The section plane defined in the Plane settings field is expressed in workpiece
coordinates. The workpiece coordinate system is the coordinate system you
define in the CMM host software. The K-CMM software automatically recalculates
the coordinates coming from the camera (CMM coordinates), to this workpiece
coordinate system with the use of a transformation matrix. To generate this
transformation matrix the K-CMM software needs to know the coordinates of
three points both in the CMM coordinate system and in the workpiece coordinate
system. Therefore two files have to be generated containing the coordinates of at
least three points in these two coordinate systems. Currently this option is only
implemented to work with files, exported from the CMM-software Metromec©.
The file containing the coordinates of the points in CMM coordinates should be
specified in the Machine field. Here’s an example of the contents of such a file
(containing the coordinates of four points):

Plane settings
The plane settings define the section plane you want to measure in:
• Specify which plane your section plane is parallel to.
• Specify the distance from this plane to your section plane.
Important: The plane settings have to be expressed in the workpiece coordinate
system. The workpiece coordinate system is the coordinate system you define in
your CMM host software. The K-CMM software automatically recalculates the
coordinates coming from the camera (CMM coordinates), to this workpiece
coordinate system, based on a transformation matrix generated from the files
filled out in the Alignment field.
Tolerance
The tolerance value defines the offset from the hole’s plane within which
measurement points will be taken. When the probe is moved to a greater
distance from the section plane no measurement points will be taken.
Distance Trigger
When using the Profile measurement function, the K-CMM software will
automatically take measurement points when the probe is within the tolerance
region from the section plane. A new measurement point is taken each time the
probe is moved a certain distance within this tolerance region. This distance is
defined by the Distance trigger value.
Activate
When all the settings are filled in correctly, click the Activate button to activate
the Profile measurement function.

The HOLE MEASUREMENT button
The Hole measurement function is a tool that helps you to measure holes in
sheet metal. The difficulty in measuring holes is to position the probe tip on the
border of the sheet metal.
The K-CMM software helps you with this in a way that measuring holes becomes
very easy. You simply measure a plane that is parallel to the hole and specify an
offset from this plane to define the plane in which you want to measure the
diameter. When starting your measurements you can simply move the probe in
and out of the hole along the side of the hole. The K-CMM software will
automatically take measurement points each time you cross the specified plane.
With the Tolerance option you can specify a tolerance field around the plane of
the hole, within which measurement points should be taken.
A measurement point is automatically taken each time the probe tip is moved a
certain distance away from the last point. This distance is specified by the
Distance Trigger option.
For step-by-step instructions on how to perform a Hole Measurement refer
to the chapter
2.2.10 How do I do a hole measurement using only K-CMM
When you click on the HOLE MEASUREMENT button in the K-CMM Main
screen the following screen appears.
KRYPTON Help Pages on K-CMM
Page 53 / 79
Measure plane
To specify a plane that is parallel to the plane of the hole you want to measure,
you should measure three points. Click on this button to start measuring the three
points that will define this plane.
Offset
When you have measured a plane that is parallel to the plane of the hole, you
can specify the distance from this plane to the plane of the hole. This distance is
defined by the Offset value.
Tolerance
The tolerance value defines the offset from the section plane within which
measurement points will be taken. When the probe is moved to a greater
distance from the section plane no measurement points will be taken.
Distance Trigger
When using the Hole Measurement function the K-CMM software will
automatically take measurement points belonging to the hole, when the probe is
within the tolerance region from the hole’s plane. A new measurement point is
taken each time the probe is moved a certain distance within this tolerance
region. This distance is defined by the Distance Trigger value.
Activate
When all the settings are filled in correctly, click the Activate button to activate
the Hole measurement function.
Cancel
The Cancel button exits the Hole settings menu without activating the Hole

The JUMP button
The Jump function allows enlarging the measurement volume by repositioning
the camera and using intermediate points as reference points. This enables you
to do measurements on one workpiece with several camera positions. This can
solve invisibility of the markers for the camera, caused by obstacles.
The principle the Jump function is based on, is that at least three points are
measured twice from different camera positions. The K-CMM software can
calculate a common reference frame from these measurements. When
measuring points with the camera in the new position K-CMM will automatically
recalculate the coordinates to the coordinate system of the old camera position.
KRYPTON Help Pages on K-CMM
Page 54 / 79
This way, the CMM host software will receive all coordinates according to the
original coordinate system (the one of the first camera position). The Jump
function is said to be transparent, as the CMM software does not notice the
camera jump.
For a step-by-step description of the procedure refer to chapter
2.2.4 How to perform a camera JUMP
When you click the JUMP button in the K-CMM Main screen the following screen
appears:
New jump
When you have measured some intermediate points in one camera position,
these points have to be measured again in the new camera position so the KCMM software can calculate a transformation matrix.
So once the intermediate points are measured in the first camera position, click
on the New jump button to start measuring these points again in the new camera
position.
Point
This area shows the points you have measured and that are to be used to
calculate the jump transformation matrix.
A colored dot next to the point’s number indicates the status of the point:
KRYPTON Help Pages on K-CMM
Page 55 / 79
• A red dot
indicates that the point has been measured in the first camera
position but hasn’t been measured in the second position.
• A green dot indicates that the point has been measured in the first as well
as in the second camera position.
• A blue dot
indicates that the point is to be left out in the calculation of the
best fit of the two sets of points.
Residual
In this area the total Residual value is given. The residual is the difference
between the theoretical value of a coordinate and the measured value after a
best fit.
When this value is high it is likely possible that an error has been made. Possibly
two points are not corresponding. You missed one point in the sequence or you
measured a wrong point. As a rule of thumb, you could say that residual values of
less than 0,1 mm are acceptable. Depending on the application, residual values
up to 0,25 mm can be accepted as well.
Residual bar
The blue bar that appears beneath the measured points indicates the overall
Residual. The scale of this bar can be changed by clicking the arrow buttons.
Extra functions
To select the point on which you want to apply one of these functions, select it by
clicking it with the mouse. This point becomes marked in blue and it becomes the
active point.
•
Delete point
This function removes the active point from the list.
! To be used with care !
•
Mark point
The active point will not be taken into account for the calculation of the best fit of
the two sets of points. Instead of displaying the residual, DISABLED is shown in
the Residual column of the point and the colored dot changes to blue.
If the residuals are too high, you can try to disable the point with the maximum
residual. If afterwards all the residuals are fine, it means that the disabled point
was not measured in the right way. The disabled point can be measured again by
clicking on it with the mouse.
•
Edit point
Allows creating a theoretical point or set of points and can also be used to edit
existing points.
To add a theoretical point, go to the end of the point list and click on ‘New point’
to activate it and next click the Edit point button to create the new point.
To edit an existing point make this point active by clicking it and press the Edit
point button to edit it.

OK
When you have completed measuring the points necessary for the camera jump,
click the OK button to activate the jump function. From this point on, the
coordinates sent to the CMM host program will be recalculated to the reference
system of the first camera position.
The CALIBRATE PROBE button
The CALIBRATE PROBE button launches the Probe Calibration software to
calibrate the SpaceProbe. This program requires some measurements in order
to derive the relation between the markers on the probe and the probe tip
mounted on the probe. The result of a probe calibration is stored in a tip
database. This tip database can be found in the <User settings> in the <Settings
menu>. It contains the calibration data for all tips that have been calibrated so far.
When a probe tip is mounted, that has already been calibrated before, the K
CMM software will automatically detect this probe tip and load the according
calibration data out of the tip database.
Two calibration steps have to be taken:
•
•
Origin Calibration: This step reveals the position of the probe tip with
respect to the LEDs.
Direction Alignment: This step is necessary to identify the probe tip direction
in order to calculate the tip radius compensation. The following picture
declares what is meant by the probe tip direction.
KRYPTON Help Pages on K-CMM
Page 57 / 79
The first case, a straight tip without any corners, is the ‘default’ case. This means
that if no direction alignment is done, a perfectly straight tip will be assumed (so
in case you have a straight tip, it’s advisable to not do this direction alignment so
the direction of the probe tip is defined theoretically as being straight).
For a step-by-step description of the calibration procedure, refer to chapter
2.2.1 How to calibrate a probe
The user interface of the probe calibration software is as follows:
Visibility of the markers
These colored buttons are red or green when the markers are invisible or visible
for the measurement system. The lowest button represents the trigger button that
determines when a measurement has to be taken.
Number of measured points
This figure shows how many points have been measured so far.
KRYPTON Help Pages on K-CMM
Page 58 / 79
Origin calibration quality
These two colored bars that appear when an origin calibration is performed, give
an indication of the quality of the excitation in two perpendicular planes. The
value underneath each of these bars indicates the angle in which the probe has
been excitated in that specific direction. Both bars have to be green to guarantee
a good quality of the calibration.
Probe tip uncertainty
This colored bar gives an indication of the uncertainty on the probe tip position
with respect to the markers during origin calibration. The value underneath gives
an indication of the maximal residual error on the calibration so far. The higher
this bar becomes the lower the quality of the origin calibration.
Origin calibration
For the origin calibration the markers shall be rotated around the probe tip, which
is held fixed in a fixture. Via this rotation the markers shall be brought to several
(at least 10) measuring points that are more or less divided over half a sphere.
Use the trigger (interior) button to take a measurement. On the screen you can
follow the number of points already taken. Make sure you rotate significantly
around the three axes of the probe frame.

Monitor
This button brings up a little window with the real time coordinates of the probe.
These coordinates are expressed in the camera coordinate system.
The direction of the probe (Dir X, Dir Y, Dir Z) shows in which way the probe is
held.
The residue shows the maximum residual error between the calibration data and
the currently measured positions of the markers on the probe.
Direction alignment
The direction alignment will identify the probe tip direction.
To perform the direction alignment, at least two points shall be measured.
Between each point the probe is moved away from the material.
Notice: The Monitor button and the Direction Alignment button are by default
inactive. They only become active after an Origin Calibration has been done or
when the previous calibration of the active probe has been imported. To import
this calibration, go to the Probe menu and click Activate to remove the checkmark
and deactivate the probe. Now go into the Probe menu again and click Import.
The previous calibration of the probe is now loaded again.

Scanning
With the K-CMM system, a scanning mode is possible. This means that
measurements are taken continuously while moving the probe tip.
Three different ways of triggering the measurements in scanning mode are
possible:
•
•
•
Continuous measurement: measures points at the maximum frequency.
Time triggered: takes trigger points with a certain time interval, which is set
by the parameter (in ms).
Distance triggered: This mode triggers measurement points at equal
distances from each other. If it is set at a distance of 50mm, trigger points
will be taken every time the probe tip is moved more than 50mm in a 3D
volume. This method always gives a number of points, independent from
the probe’s speed.
Notice: In the scanning mode you should check whether the measurement
software and the selected interface protocol can keep up with the processing of
the amount of measurement data.
Pressing the Function button on the probe activates the scanning mode.
Therefore this button must be configured for the scanning mode (see Function
button function). When you’re in scanning mode you can start taking
measurement points by pressing the Trigger button. To stop taking measurement
points, press the trigger button again.
When the scanning mode is active, the red light in the Function button lights up
and the Mode window in the K-CMM main screen will say ‘Scanning mode’.

3.1.6.2
Dynamic reference
The dynamic reference function allows you to define a coordinate system based
on markers mounted on your workpiece. This can be extremely useful when you
need to move your camera or when the floor is unstable. By using the dynamic
reference function you can make sure that the coordinates that are sent to the
CMM host software, are always expressed in the same reference system,
independent from the position of the workpiece in relation to the camera.
In the Dynamic reference tab you can choose to activate the dynamic reference
option. The following options have to be specified:
•
•
•
Maximum deformation: the K-CMM program will display an error message in
the Information window and prohibit the taking of measurement points,
when the movement of the markers that serve as dynamic reference, in
relation to each other, exceeds this value.
Maximum displacement: the K-CMM program will display an error message
when the movement of the markers that serve as dynamic reference, in
relation to the camera, exceeds this value while less than three markers are
visible for the camera.
Number of markers / omni-dir. references: the amount of normal markers
(bare LEDs) or omnidirectional probes used to define the dynamic reference
system.
For the reference points, used to make the dynamic reference, there are two
possibilities:
•
•
Use markers: choose this option if you are going to use normal markers to
make the dynamic reference.
Use omnidirectional references: choose this option if you are going to use
omnidirectional references to make the dynamic reference. Note that these
omnidirectional references have to be calibrated before they can be used.
The appropriate calibration file has to be entered here. For a description of
how to calibrate these omnidirectional references read the chapter
2.2.6 How to use a omnidirectional reference
In the “Active Reference” field you must enter the name of the file in which the
active reference has to be saved.
Once you defined a dynamic reference you can work with this dynamic reference
later on by filling in the appropriate filename or clicking the Load button.
For a detailed description read the chapter
2.2.3 How to use a Dynamic Reference
3.1.6.3
Image
The image function allows you to take an ‘image’ of the coordinates of several
LEDs (markers), attached to your workpiece. In other words, when activated in
the software, the image function will measure the coordinates of LEDs attached
KRYPTON Help Pages on K-CMM
Page 66 / 79
to your workpiece and send these coordinates to the CMM host software as
measurement points.
This can be very convenient when you want to measure several points in different
situations very quickly. The software will scan for the markers on your workpiece
and determine the coordinates very fast. You then change your workpiece into
the next situation you want to measure these points in. The K-CMM software will
then scan for the markers again and determine the new coordinates of these
markers.
To activate the image mode put a check mark at ‘Activate Image Mode’ in the
Image tab in the <Settings><User settings> menu. In the K-CMM main screen
the IMAGE status window will turn green indicating that the Image function is
active. When starting your measurements (by clicking the START MEASURING
button) the K-CMM software will automatically start scanning for the LEDs used
for the active image mode and send the coordinates of these LEDs to your CMM
host software.
In the Image tab you must specify the amount of LEDs (markers) that are
attached to each of the ports of the LED controller. The first port is not available
for the image mode; this port is reserved for the LEDs of the SpaceProbe. On the
second, third and fourth port (called respectively Dynamic Reference, Image 1
and Image 2 in the Image tab) the LEDs for the image mode can be connected.
To measure the coordinates of the markers repeatedly in certain time- or
distance-steps, there is a special Triggering option available in the image
function:
•
•
•
Distance trigger: If you want to measure the coordinates of the markers in
several positions of the workpiece, you can use the ‘Activate Distance
trigger’ option. When this option is enabled, the software will measure the
positions of all the LEDs, each time the first of the LEDs, used for the
image, moves more than the specified distance.
Time trigger: To measure the coordinates of the markers repeatedly in
time, you can activate the Time trigger. Here the software will measure
the positions of all the LEDs with a certain time interval you can specify.
No trigger: To measure the coordinates of the markers only once after you
have started the K CMM software, you can choose for no trigger.
When, during the measurement of several LEDs, certain LEDs are invisible, the
software will send a zero value for the coordinate of these LEDs. In some cases
however, you do not want to have these zero values of invisible LEDs in your
measurements. Therefore you can activate the ‘Do not send invisible points as
measurement points’ checkbox.
For a detailed description read the chapter
2.2.7 How to use the Image function
3.1.6.4
Workpiece compensation
To preserve the accuracy when measuring in different temperature conditions,
a workpiece compensation option is foreseen in the K-CMM software.
KRYPTON Help Pages on K-CMM
Page 67 / 79
In the Workpiece compensation tab you can activate this temperature
compensation. You have to specify the Workpiece material (steel or aluminum) or
enter a thermal expansion coefficient. You also have to specify the reference
temperature to which your measurements should be recalculated.
Important: When using the workpiece temperature compensation, you should
have external temperature sensors connected to the camera system. If your
camera system isn’t equipped with these temperature sensors you can manually
enter the workpiece temperature. Fill in the workpiece temperature in the
‘Workpiece temperature’ field and put a checkmark to activate this option. Your
measurements will then be recalculated from this temperature to the reference
temperature.

software can communicate with the host CMM software. To edit the settings
for this COM-port click on the Port Settings button. A screen will appear in
KRYPTON Help Pages on K-CMM
Page 68 / 79
•
•
•
•
which you can specify the values concerning the communication via this
COM-port.
Protocol: To communicate with the CMM host program, the K-CMM
software uses a certain protocol that is described in a script file. In this field
you can specify which script file the K-CMM software should use to
communicate with the CMM host program. A number of scripts for use with
several CMM host programs are provided with the K-CMM software. To edit
this script file or to create your own script file, click on the Edit button. For a
detailed description of the script language refer to the Script language page.
Calibration: When a probe has to be calibrated the K-CMM software will
start the ProbeCalibration software. In this field you can specify which
ProbeCalibration program should be used.
Language: To switch to a different language, select the language from the
list of available languages in the drop down list.
Probe COM-port: Here you can specify which COM-port on your PC the
probe is connected to.
Important: Make sure the COM-port and the Probe COM-port fields are filled in
correctly. Specifying a wrong COM-port here will cause the K-CMM software to
work incorrectly.
3.1.7.3
Measurement Parameters
In this tab you can specify some parameters concerning your measurements:
•
•
Allow orange led measurements: While measuring with the probe, a tri
colored LED will indicate the quality of your measurement. When the LED is
green the measurement will be acceptable, when the LED is red the
measurement will be unacceptable and the K-CMM will not send the
measured value to the CMM host program. When the measurement is on
the edge of the tolerance range the tri colored LED will be orange. You can
choose to accept these measurements by placing a check mark at the Allow
orange led measurements option. By de-activating this option the ‘orange
led measurements’ will not be accepted.
Activate TurbuLED: In an industrial environment it is not always easy to
create an optimal measurement condition to perform very accurate
measurements. The stability of the environment can be influenced by a lot
of factors such as vibrations, exaggerated temperature drift, airflows, etc.
These influences are difficult to detect and hence often ignored while
performing measurements. Krypton has developed a way to detect these
“turbulences” that can influence the measurements. This solution consists of
an extra marker, mounted on the measurement object. This TurbuLED, as it
is called, is constantly monitored to detect any bad influences on the
measurement conditions. A colored bar in the K CMM software gives an
indication of the turbulences and a warning message is shown if a certain
level is passed.
When using the TurbuLED three parameters have to be entered:
− Position Tolerance (mm): if the position of the TurbuLED changes more
than this tolerance an error message “Environment not stable” will appear.
Also the Feedback Led on the SpaceProbe will become orange and
KRYPTON Help Pages on K-CMM
Page 69 / 79
measurements are only possible if the ‘Allow orange LED measurements’
is enabled in the <Measurement Parameters> tab.
− Standard Deviation (mm): if the standard deviation on the position of the
TurbuLED changes more than this value during the measurement of a
point with the SpaceProbe, an error message “Environment not stable” will
appear. Also the Feedback Led on the SpaceProbe will become orange
and measurements are only possible if the ‘Allow orange LED
measurements’ is enabled in the <Measurement Parameters> tab.
− Maximum Peak Duration (s): if one of the previous tolerances is passed
longer than the specified time (e.g. in case the measurement part has
moved) the error message “Environment not stable” appears. The
Feedback Led on the SpaceProbe will become red and no further
measurements are possible.
3.1.7.4
K Reference
In this menu you can enter the name of the so-called Trigger file. This is the file in
which the measurement points, which are taken during the measurement of the K
Reference bar, are stored.
3.1.7.5
Tip Database
When a new probe tip is calibrated, the calibration information is stored in a Tip
database. This screen gives an overview of the different tips in the database
along with some additional info (such as when the tip was calibrated, the name of
the tip, …).
The probe diameter appearing in the last column of the Tip Database, can be
given to the CMM host software via a variable called #TipRadius in the script file
The probe diameter is set by standard to 10 mm. To change the diameter of the
probe tip simply click on the diameter and enter the correct value.
In order to prevent the K-CMM software to automatically detect the probe tip, you
can put a checkmark at the ‘De-activate Automatic Detection’ option. You can
now select the calibration data that has to be used by selecting a tip from the tip
database.
3.1.8
Alphabetic list of messages/error messages
Camera too cold! (LS1)

software. ( higher than 60°C )
KRYPTON Help Pages on K-CMM
Page 70 / 79
Environment too cold!
This error message is displayed when an external temperature sensor is used in
CMM and this sensor experiences a temperature that is lower than the value set
in the software. ( lower than 10°C )
Environment too hot!
This error message is displayed when an external temperature sensor is used in
CMM and this sensor experiences a temperature that is higher than the value set
in the software. ( higher than 35°C )
Environment Unstable!
When during the use of the TurbuLED, the TurbuLED is moved more than the
value the user has specified as “position tolerance”, this error message is
displayed.
Initialising Temperature Sensors
This is not an error message. The message appears every time the temperature
sensors in the probe are being initialized.
No Initial Reference Frame
When the TurbuLED option is activated in the software, this message will be
displayed when CMM has been started. Once the TurbuLED has been calibrated,
this message disappears. ( See TubuLED procedure p. )
No probe tip inserted!
This message is displayed when CMM is started and there is no probetip
screwed onto the SpaceProbe.
Probe is invisible
This message will appear every time the probe is invisible for the camera. If the
probe is made visible this message disappears.
Probe is not calibrated
If this message appears and the red feedback light on the probe stays red even
when the probe is visible for the camera, it means the probe was not calibrated.
You have to calibrate the probe tip in order to be able to work with it.
Probe out of border
This message will appear every time the user tries to measure a point while the
probe is invisible for the camera.
Probe tip was not stable
This message will appear every time the user moves during the measurement.
The measurement will not be accepted by CMM.
Probe too cold! (LS1)
Error message can also be Probe too cold! (LS2), Probe too cold! (LS3) or Probe
too cold! (LS3). This error message is displayed when one of the temperature
KRYPTON Help Pages on K-CMM
Page 71 / 79
sensors in the probe experiences a temperature that is lower than the value set in
the software. ( lower than 10°C )
Probe too hot! (LS1)
Error message can also be Probe too hot! (LS2), Probe too hot! (LS3) or Probe
too hot! (LS3). This error message is displayed when one of the temperature
sensors in the probe experiences a temperature that is higher than the value set
in the software. ( higher than 35°C )
Reading Tip Number...
This is not an error message. It will appear whenever a new tip is being screwed
onto the probe. After this message, the probe calibration program will be started
automatically if the probe has not been calibrated before. If the probe has been
calibrated before, you will get the following window.
The software then allows you to re-use the old calibration or to do a new
calibration.
Recalibrating Probe...
This is not an error message. When a new tip is being screwed onto the probe he
will read the probe tip number. After this message, the probe calibration program
will be started automatically if the probe has not been calibrated before.
Reference has moved
This message appears when during the use of a Dynamic Reference the
measurement object is moved. As soon as the object stands still and all LEDs are
visible again the message disappears.
Reference invisible
This message appears when during the use of a Dynamic Reference all the LEDs
on the measurement object are invisible to the camera. Measurement points will
not be accepted when this message is being displayed.
KRYPTON Help Pages on K-CMM
Page 72 / 79
Reference is deformed
This message appears when during the use of a Dynamic Reference the position
of the LEDs on the measurement object is changed. (e.i. the object is deformed).
Measurement points will not be accepted when this message is being displayed.
This problem can also occur when value for maximum deformation is not set to a
sufficient level. In that case see if increasing the maximum deformation value
( in CMM User settings/ Dynamic reference ) solves the problem.
Reference is not optimal.
At least three markers are needed to create a dynamic reference. If you use more
than three markers, it is allowed that markers become invisible. The only
conditions that have to be fulfilled are that at least three markers stay visible and
that the visible markers form a “not too sharp” triangle. More specific, the largest
base of the triangle must be smaller than four times the height of this triangle. If
this is not the case the message “ Reference is not optimal “ will be displayed.
To solve the problem:
Try to position the LEDs differently on the object
Starting Probe & Camera...
This message is not an error message. It is displayed every time CMM is started.
TurbuLED not calibrated!
This message will appear when the TurbuLED option has been enabled but the
TurbuLED hs not been calibrated yet.
To solve the problem:
Calibrate the TurbuLED. You can find the
procedure on p. 25 in this manual.
Temp. changing too fast!
This message appears when the temperature gradient of the probe, camera or of
the external temperature sensor is changing too fast.
Warning: camera failure.
This message will appear when the connection with the camera has been lost.
To solve the problem:
See if the camera cable is not disconnected, if
necessary start-up K-link again and restart CMM

Feedback lights explanation
• Feedback lights: with the feedback lights the colored LEDs on the probe are
meant. These LEDs give you some visual information about your
measurements. The following picture shows the feedback lights on the
probe.
3.2.1.1
Light on function button
•
•
Is extinguished during normal operation.
Is colored red, when the scanning function is activated. Depending on the
software settings of the function button, scanning mode can be activated
by pushing this function button.
KRYPTON Help Pages on K-CMM
Page 74 / 79
3.2.1.2
Tri-colored feedback light
Can be colored:
Red
•
This means measuring is not possible ( Probe is not visible, Dynamic
reference is deformed etc…. )
Orange
•
Measurement is still possible but the accuracy is not optimal. E.g. the
probe is not held parallel to the camera but held under an angle.
Green
•
3.2.1.3
Measurements are possible and accuracy is normal.
Red feedback light
With red feedback light is meant, the feedback light right beneath the tri-colored
LED.
• This red light will blink once every time a point has been measured and
accepted by CMM.
• This red light will blink fast whenever a point was measured but not
accepted by CMM. E.g. the probe was not visible or the operator moved
during the measurement. Along with this blinking the operator will also get
an audible signal.
• The red light can also blink slowly, this can happen during the use of a
Dynamic Reference when the reference has moved and the camera
needs to see all LEDs again to determine the new position of the object.
Once this is done the feedback light will turn green again.
3.2.2
Feedback lights troubleshooting
No Feedback light on the probe
•
•
•
•
•
Make sure the probe is connected to K CMM. If this is not the case the
software will indicate " error trying to initialize probe " when you try to start
it.
Make sure K CMM is started.
When you’re using KCheck the feedback light will not be lit.
Make sure a probe tip is screwed onto the SpaceProbe. If this is not the
case K CMM will indicate " No Probe tip Inserted ".
If no feedback light is visible stop K CMM and use Probe check to check if
the probe is functioning or not.
Only red Feedback light on the probe
•
Hold the SpaceProbe inside the camera field with its LED’s directed to the
camera. Make sure the lens covers are removed. If the probe is not visible
the software will indicate " Probe invisible " and the LED will remain red.
KRYPTON Help Pages on K-CMM
Page 75 / 79
•
•
If you’re using a DR check if this is still working. In case of problems, the
software will say " Reference invisible " or "Reference has deformed " and
the DR symbol will be colored red in K CMM. Make sure the DR are
attached via a strober and a cable to one of the front ports of the
controller (not to port 1!)
If the probe tip is not calibrated or the residual is too high, the LED will
remain red. Calibrate the probe tip to solve this.
